Product details
Overview
AOZ8234DI-05 from Alpha and Omega Semiconductor is a four-line unidirectional/bidirectional TVS diode array for ESD and transient protection of high-speed data lines. It features 5.0 V working voltage, ±18 kV IEC 61000-4-2 contact/air discharge rating, 13.5–16.0 pF junction capacitance, and low 12.0 V / –10.0 V clamping at 15 A, used in portable GPS and digital camera interface protection.
For engineers reviewing the AOZ8234DI-05 datasheet, pinout, applications, or equivalent options, key selection factors include bidirectional vs. unidirectional line configuration, DFN 1.45 × 1.0 mm package constraints, clamping voltage under 15 A transients, and compatibility with IEC 61000-4-2 Level 4 ESD immunity requirements.
Technical Context
The AOZ8234DI-05 implements Trench Vertical Structure [TVS]²™ technology to achieve low clamping voltage and fast response during ESD events. Its dual-mode configuration supports either four unidirectional I/O lines (pins 1/3/4/6 to signal, pin 2 to ground) or two bidirectional lines (pins 1/3 to signal, pins 4/6 to ground).
It operates across –40 °C to +85 °C ambient, with 5.0 V reverse working voltage and 6.0 V minimum breakdown voltage at 1 mA. Junction capacitance remains below 16.0 pF at 0 V bias, enabling use on USB 2.0 and HDMI data paths without signal integrity degradation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Working Voltage (VRWM) | 5.0 V - matches standard 5 V logic and interface supply rails without overvoltage risk |
| Clamp Voltage (VCL) | 12.0 V / –10.0 V at 15 A - limits transient energy delivered to protected ICs within safe voltage margins |
| Junction Capacitance (Cj) | 13.5–16.0 pF at 0 V - preserves signal integrity on high-speed lines up to ~500 Mbps |
| ESD Rating (IEC 61000-4-2) | ±18 kV contact / ±18 kV air - exceeds Level 4 immunity requirement for handheld consumer devices |
| Peak Pulse Current (IPP) | 4 A at 8/20 µs - handles common surge waveforms in portable electronics interfaces |
| Package Dimensions | 1.45 mm × 1.0 mm × 0.55 mm DFN - enables placement near connectors in space-constrained PCB layouts |
Pinout & Package
AOZ8234DI-05 uses a RoHS-compliant, lead-free DFN 1.45 × 1.0 mm, 6-lead package with exposed thermal pad (not electrically connected). Pin 1 is marked by dot; pin numbering follows top-view clockwise sequence starting from dot corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | I/O1 (unidir) / CH1 (bidir) | Primary protected signal line; connects to data line requiring ESD suppression |
| 2 | GND (unidir) / NC (bidir) | Dedicated ground return for unidirectional mode; no connection in bidirectional configuration |
| 3 | I/O2 (unidir) / CH2 (bidir) | Second protected signal line; shares same clamping path as Pin 1 in bidirectional mode |
| 4 | GND (unidir) / GND (bidir) | Secondary ground terminal; required for low-inductance grounding in bidirectional mode |
| 6 | I/O4 (unidir) / GND (bidir) | Fourth signal line in unidirectional mode; serves as second ground in bidirectional mode |
Key Features
| Feature | Design Value |
|---|---|
| Trench Vertical Structure [TVS]²™ technology | Enables sub-12 V clamping at 15 A while maintaining <16 pF capacitance for high-speed data integrity |
| Configurable protection topology | Supports either four unidirectional lines or two bidirectional lines via PCB routing-no component change needed |
| Low clamping voltage | 12.0 V positive / –10.0 V negative clamp at 15 A ensures downstream ICs remain within absolute maximum ratings |
| Ultra-small DFN footprint | 1.45 mm × 1.0 mm area saves >60% board space versus SOIC-8 TVS arrays, critical for thin portable designs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS diode array applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA6J5.0A | Single-channel SMA package; 5.0 V VRWM, 17.1 V VCL at 10 A; 100 pF Cj | Requires four discrete devices for four-line protection; unsuitable for high-speed interfaces due to high capacitance | Select when board space is unconstrained and only basic ESD protection is needed on low-frequency lines. |
| TPD4E05U06DQAR | Quad-channel, 0.65 mm × 1.0 mm DFN; 5.0 V VRWM; 12.5 V VCL at 12 A; 0.5 pF Cj per channel | Lower capacitance ideal for USB 3.0/PCIe; lower peak current rating (12 A vs. 15 A) | Prefer for next-gen high-speed interfaces where <1 pF loading is mandatory; verify layout compatibility with smaller pad pitch. |
Compared with SMA6J5.0A and TPD4E05U06DQAR, the AOZ8234DI-05 delivers balanced performance: moderate capacitance (13.5–16.0 pF) suitable for USB 2.0/HDMI, higher 15 A clamping capability than TPD4E05U06DQAR, and integrated quad-channel packaging unlike SMA6J5.0A's discrete approach.

FAQ
What is the maximum operating temperature range for the AOZ8234DI-05?
The AOZ8234DI-05 is rated for operation from –40 °C to +85 °C ambient temperature. Its junction temperature range extends to –40 °C to +125 °C, allowing reliable performance in portable devices subject to internal self-heating. This range aligns with industrial and consumer-grade portable electronics specifications, and the DFN package's thermal characteristics support stable operation without derating under typical PCB copper pour conditions.
How does the AOZ8234DI-05 support both unidirectional and bidirectional protection configurations?
The AOZ8234DI-05 supports dual configurations through its pin assignment: for unidirectional protection, pins 1/3/4/6 connect to four data lines and pin 2 to ground; for bidirectional, pins 1/3 serve as protected lines while pins 4/6 become ground terminals. This flexibility eliminates the need for separate part numbers. The internal diode architecture enables symmetrical clamping in bidirectional mode without external components, verified per IEC 61000-4-2 testing in both polarities.
What is the clamping voltage of the AOZ8234DI-05 under a 15 A transient pulse?
The AOZ8234DI-05 exhibits a clamping voltage of 12.0 V for positive transients and –10.0 V for negative transients at IPP = 15 A and tp = 100 ns. These values are measured per IEC 61000-4-5 waveform conditions and ensure downstream ICs remain within safe operating limits. The asymmetry reflects optimized forward/reverse conduction characteristics of the trench vertical structure, and the specification is guaranteed across the full –40 °C to +85 °C operating range.
Is the AOZ8234DI-05 compliant with RoHS and halogen-free standards?
Yes, the AOZ8234DI-05 is an AOS Green Product: it is fully RoHS compliant and halogen-free, meeting JEDEC JS709B and IPC-4101D requirements. The DFN package uses lead-free terminations and contains no brominated flame retardants or antimony trioxide. Compliance documentation, including material declarations and test reports, is available upon request from Aetrix Electronics for full supply chain traceability and regulatory reporting.
What is the typical junction capacitance of the AOZ8234DI-05 and how does it affect high-speed signal lines?
The AOZ8234DI-05 has a typical junction capacitance of 13.5–16.0 pF per channel at 0 V bias and 1 MHz. This value is low enough to avoid measurable rise-time degradation on USB 2.0 (480 Mbps) and HDMI 1.4 (up to 3.4 Gbps) data lanes when placed with short trace lengths. Layout best practices-such as direct ground plane connection and minimized loop area-ensure the specified capacitance translates to real-world signal integrity retention without equalization or re-timing.
